The IPFS Proxy has been tested by me. And with the IPFS Proxy, I can already operate the IPFS-cluster. However, A cluster of clusters has not been successfully built. So I want to ask, how did the main cluster and sub-clusters communicate? What is the configuration details? ---

You need to set the `node_multiaddress` of the “overcluster” peers to the proxy endpoint of the subclusters. So that a peer from the main cluster would use another pear from a subcluster instead of the ipfs daemon. ---

Let us know of your experience. We haven’t tested composite clusters much.
